Oops I meant to refer to the AP7 series specifically. I haven't looked into ucLinux, thanks for mentioning it. I'll take a look at it asap as I'm quickly becoming a fan of the ST32.
that's like saying ''cortex has it''. AVR32 is an architecture, not a specific implementation. AP7 devices (no flash) run linux, but UC3 devices (controller-like, with flash, ADC, etc) don't. linux needs an MMU and neither UC3 nor STM32 have it, but you could run uClinux on both.
